Guild Wars 2

Problems started this sunday. My PC automaticly updated new windows 10 version and since than, i have crazy lag spikes (skill delay over 10 seconds) usualy ending with DCs.
What i know:
- All DC codes were conection related (can’t remember full codes now, but usualy starting with 11:…)
- DCs happening on anywhere from 40 to 4.000 ping (never had ping issues befour, and it never went over 100. My usual ping is 40-60 and game was working fine even when it was up to 90-100)
- It happens in raids mostly (like 90 % of DCs), but yesterday stated in fotm and dungens as well (not that offten as in raids)
What i tried to do:
- Updated patches, turned off green ethernet, turned off all backgorund running programs, updates, etc… Still same problem.
- Finaly, yesterday i restored previous version of windows 10. Didn’t help.
What elese can i try? Its realy not good when you lay dead on 5 of 9 booses in raids cause of DCs.
One problem that i didn’t adress yet is relativly high temperature of PC when im playing GW2. Don’t know if that might be issue, cause PC is new (few months old), with Intel i-5 CPU, 8 RAM, etc… it should be fine, but…
Ideas?

PS. I tested ping on speedtest and it was 24-26. Does that mean those DCs are not conection related?

your pc is a laptop or desktop? check your temperature while playing gw2 using a program like speccy/cpu-z

also check your windows fire wall settings to make sure guild wars2 can get onto the

internet all together .as windows10 firewall will block guild wars2
